Complex number

In mathematics, a complex number is an element of a number system that extends the real numbers with a specific element denoted i, called the imaginary unit and satisfying the equation ; every complex number can be expressed in the form, where a and b are real numbers. Because no real number satisfies the above equation, i was called an imaginary number by René Descartes. For the complex number, a is called the real part, and b is called the imaginary part. The set of complex numbers is denoted by either of the symbols or C. Despite the historical nomenclature, "imaginary" complex numbers have a mathematical existence as firm as that of the real numbers, and they are fundamental tools in the scientific description of the natural world.

How do you find the sum of the unit vectors

(- 9, 12, - 5)

(6, 5, - 5)

(- 9, 12, - 5)

(6, 5, - 5)

are not unit vectors; therefore this question is meaningless.

What is the distance between

(- 2, 1, 14)

(- 12, 2, - 5)

https://socratic.org/questions/what-is-the-distance-between-2-1-14-and-12-2-5

See a solution process below: Explanation: The formula for calculating the distance between two points is:

d = ((x_{2}) - (x_{1}))^{2} + ((y_{2}) - (y_{1}))^{2} + ((z_{2}) - (z_{1}))^{2}

Opposite sign, why?

https://math.stackexchange.com/questions/1005019/7i2-5i-opposite-sign-why

7i(2-5i) = 7i*2+7i*(-5i) 7i(2) = 14i 7i * (-5i) = -35*i^2 = -35*(-1) = 35 So, the solution is 14i+35

Explanation: The slope of the line passing through (-8,2)and (-12.-20)is

\frac{- 2 0 - 2}{- 1 2 + 8} = - \frac{2 2}{- 4} = \frac{1 1}{2}
